Research

Intravacc is continuously investing in R&D platforms to facilitate vaccine development. Early development includes vaccine strain design to generate bacterial, viral and cellular seeds for efficient vaccine production.

We also carry out studies on adjuvants and delivery systems, resulting in safe products that are efficacious.

Our successful R&D efforts are then further developed into services we offer to clients.

To investigate the efficacy of vaccines, Intravacc performs immunological research to unravel the mechanisms of action of vaccine concepts. These immunological assays are used during preclinical and clinical stages.

Process Development

We can apply our long-standing and extensive experience in vaccine development to design rational and modelled processes together with our clients.

Using mathematical models we can safely scale from lab to commercial scale bioreactors.

Viral vaccine R&D

Focusing on the treatment or prevention of viral diseases such as Polio, Respiratory Syncytial Virus, Enterovirus, Influenza, Rabies and Rotavirus. We have access to a qualified Vero cell line and specialized equipment to perform research for WHO, the Dutch Ministry of Health and collaborate with other parties.

The quality is a decisive factor in the development of new vaccines. Intravacc uses multiple instructive assays and innovative techniques to guarantee the quality of intermediates and finished product. Our tests focus on the composition, concentration, efficacy, purity, safety, stability and identity of the new vaccine candidate.

Immunoassays

ELISA (direct and capture assays for antibody titres in sera and antigen concentrations in vaccine formulations)

Animal models

We have developed several new methods, some of which were accepted by the European Pharmacopoeia.

In addition, we are a front runner in the development and distribution of a new paradigm in vaccine lot release testing, known as the consistency approach. To promote the implementation of this strategy, we participate in an IMI-funded European consortium on consistency testing.

Clinical & Regulatory

Innovative vaccines are mostly complex products for which there is often no clear regulatory guidance available. That is why our Regulatory and Clinical Affairs (RCA) team is involved in the development of these products right from the start.

By taking into consideration the regulatory restraints and requirements in an early phase of development, a lean transition to the next phase towards a marketed product can be made.

Our team provides regulatory support in vaccine development projects through early involvement, assessment of potential regulatory requirements, preparation of risk assessments and by seeking informal or formal scientific advice with national competent authorities.

Support varies from the preparation of pharmaceutical, preclinical, and clinical development plans and reports, to the submission of relevant regulatory dossiers (IMPD/IND, CTA) to health authorities.

Co-Development with partners

We are always open to work closely together with academia, public health organizations (WHO, BMGF), and biotech and pharmaceutical companies. This way, we benefit from each other's strengths in developing and innovating vaccines.

About Intravacc

Intravacc is an experienced R&D organization with a proven track record in vaccinology of over 100 years.
We have a wide range of expertise to independently develop vaccines from lead concept to clinical phase I/II studies as wel as our own product pipeline and patents.

Intravacc and BCHT enter into license agreement for production of a Hib conjugate vaccine

News | 12-11-2018

Intravacc and BCHT have entered into a non-exclusive license agreement for the development of a Hib conjugate vaccine within the People’s Republic of China.

Intravacc andChangchun BCHT Biotechnology Co today announced that they have entered into a non-exclusive license agreement towards the development ofa Haemophilus influenzae Type B (Hib) Conjugate Vaccine within the People’s Republic of China. By combining their strengths, the two parties can together lower the incidence of this vaccine preventable disease in China.

Through this agreement, BCHT obtained Intravacc’s unique Hib conjugate technology to further develop, produce and sell the vaccine. The vaccine consists of a Hib polysaccharide (poly-ribosylribitol phosphate, PRP) coupled to tetanus toxoid that has shown to be effective in preventing the disease. The Intravacc Hib vaccine technology has already been used for the vaccination of 100s of millions of children.The license agreement between Intravacc and BCHT will now help to reduce the incidence of Hib in Chinese children.

Of the 6 types of H influenzae, type B is responsible for more than 90% of systemic infections. Hib can cause serious illness like acute lower respiratory tract infection and bacterial meningitis. In China, for children under age of 5 years old, the incidence of meningitis caused by Hib was reported in a survey about 10.7/100 000 annually; 9.7% of these cases were fatal, and 21.4% of survivors suffered from neurological or psychological problems. The agreement between Intravacc and BCHT will help to bring this number down considerably.

‘’It’s great to hear that the innovative work of our researchers at Intravacc will contribute to the prevention of Hib in China. We are proud to partner with BCHT to prevent this disease.” said Mr Nico Oudendijk, General Director of Intravacc.

Intravacc and TherapyX partner to develop world’s first prophylactic vaccine against Gonorrhea

News | 15-10-2018

Intravacc has entered into a strategic partnership with TherapyX for the co-development of the world’s first prophylactic vaccine to provide lasting, protective immunity against Neisseria gonorrhoeae.

Intravacc is pleased to announce that it has entered into a strategic partnership with TherapyX for the co-development of NGoXIMTM, the world’s first prophylactic vaccine against infection with Neisseria gonorrhoeae. This new vaccine is intended to enhance specific adaptive immune responses that provide lasting, protective immunity against N. gonorrhoeae. NGoXIMTM is a combination of a sustained-release formulation of interleukin 12 (GneX12TM) and bacterial outer membrane vesicles (OMV) formulated for mucosal delivery.

No effective gonorrhea vaccine is currently available and the disease is known to be acquired repeatedly with apparently no development of protective immunity from previous infection. The American Centers for Disease Control and Prevention (CDC) has listed antibiotic-resistant N. gonorrhoeae as one of the top three pathogens presenting “an immediate public health threat that requires urgent and aggressive action.” A recent WHO technical consultation on vaccines against sexually transmitted infections (2017) called for renewed efforts to develop a vaccine against gonorrhea. This partnership effort is a direct response to that call.

Under the terms of the partnership agreement, TherapyX will focus efforts on IND-enabling efficacy and toxicology studies in primates while Intravacc will be responsible for the discovery and development of OMVs with improved immunogenic properties and reduced toxicity. Financial terms were not disclosed.

“We are thrilled to partner with Intravacc” said Dr. Dominick L. Auci, Vice President for Research and Development at TherapyX. “They bring over 100 years of expertise in vaccines including novel OMV technology to this important project. We couldn’t be working with a more experienced, innovative and dedicated team”.

“We are delighted to be working with TherapyX” said Mr. Nico Oudendijk, General Director of Intravacc. “The IL-12 technology they bring into the project is key to develop an efficacious vaccine against this disease.”

Serum Institute of India and Intravacc to develop Bioneedles

News | 04-06-2018

New Delhi/Bilthoven, 29th May 2018: Life Sciences and Healthcare is a vital area of collaboration for India and the Netherlands. Growing market opportunities in India, combined with the Netherlands’ strengths in Healthcare, create excellent opportunities for Indo-Dutch partnerships that address shared societal challenges with smart solutions. One of the key healthcare challenges that are being turned into Indo-Dutch collaborative solutions is vaccine delivery.

Serum Institute of India and Intravacc (part of the Netherlands Ministry of Health, Welfare and Sports) will jointly develop a novel delivery system for vaccines: Bioneedles. The Bioneedle, a tiny biodegradable mini implant, is a unique approach with ground breaking potential to transform vaccination campaigns, especially in low and middle income countries. The parties will develop Bioneedles for vaccines against measles and rubella. The Memorandum of Understanding confirming their collaboration was signed in the presence of Mark Rutte, Prime Minister of the Netherlands, Sigrid Kaag, Dutch Minister for Foreign Trade and Development Cooperation, Bruno Bruins, Dutch Minister for Medical Care and Sports, Hans de Boer, CEO, Confederation of Netherlands Industry and Employers VNO-NCW, and H.E Alphonsus Stoelinga, Ambassador of the Netherlands to India, during the Netherlands Trade Mission to India last week. The signatories were Dr Suresh Jadhav, Executive Director, Serum Institute of India and Thijs Veerman, CEO, Intravacc.

“I am happy that this MoU was signed during The Netherlands Trade mission to India. The collaboration between SII and Intravacc is a good example of a cooperation in which companies from India and The Netherlands join forces to help improve health worldwide,”Bruno Bruins, Minister for Medical Care of The Netherlands was quoted as saying.

Currently, vaccines are mostly administered through intramuscular or subcutaneous injection by needle and syringe. The use of needles however may cause pain and fear in vaccinated people, and requires trained personnel, which is not always readily available in low and middle income countries. Moreover, needle waste can be hazardous due to reuse and needle-stick injuries and, as a result, transmission of infectious diseases like hepatitis or HIV. To overcome these issues, numerous alternative vaccine administration devices and methods are currently being developed.

One of the most promising technologies in alternative vaccine delivery is a Bioneedle-based delivery device. “Vaccines play a critical role in public health globally- and for Intravacc, India is a vital market for partnerships in vaccine development. This project could potentially mark a major step towards vastly improved access to vaccines especially in low and middle income countries. We are very happy to be involved in such an innovative project with our Indian partner,” Thijs Veerman, CEO, Intravacc says.

Bioneedles are composed of a starch-like polymer, a product that is naturally degraded by the human body. The Bioneedle is administered by an implantation under the skin with an applicator. The Bioneedle matrix will degrade after implantation, which enables the release of the freeze dried vaccine. This reduces hazardous needle waste and results in a quick and pain-free delivery of the vaccine; it may even abolish the need for trained professionals to perform vaccinations – a huge benefit in developing countries where trained medical personnel is scarce. In addition, vaccines in Bioneedles are both freeze and heat stable and can be stored, transported and distributed outside any cold chain. Preclinical concepts of Bioneedles have been established with numerous vaccines, including tetanus, polio, influenza and hepatitis B. In all cases, Bioneedles filled with vaccine were able to induce potent systemic humoral immune responses against the respective antigen. Serum Institute of India and Intravacc will jointly develop Bioneedles for vaccines against Measles and Rubella. Intravacc will optimize the formulation of the vaccine and preparation of the Bioneedles and freeze drying process; Serum Institute of India will supply the MR vaccine. Both parties will search for a partner, preferably from India, for developing a suitable applicator device to administer the Bioneedles.

“We are now the world's largest vaccine manufacturer by number of doses produced. It is estimated that about 65% of the children in the world receive at least one vaccine manufactured by Serum Institute, saving millions of lives throughout the world,” says Dr Suresh Jadhav, Executive Director, Serum Institute of India. With this project we continue to build a sustainable, long-term partnership with Intravacc in our effort to manufacture affordable life-saving vaccines .”

All together this is a unique approach with ground breaking potential to transform vaccination campaigns, especially in the low and middle income countries.

Dutch Ministry of Health announces privatization of Intravacc

News | 14-05-2018

The Dutch Ministry of Health, Welfare and Sport has announced the start of the privatization process of the activities of Intravacc. Collegium Advisors is to act as lead advisor and co-ordinator of the privatization process.

Bilthoven, May 8th, 2018 - The Dutch Ministry of Health, Welfare and Sport (Ministerie van Volkgezondheid, Welzijn en Sport or MoH) has announced the start of the privatization process of the activities of Intravacc.

Intravacc (Institute for Translational Vaccinology) has a wide range of relevant expertise in independently developing vaccines from lead concept to clinical phase I/II studies, and has its own product pipeline and patents. Moreover, it provides and contracts R&D services to a range of public and private customers. During the last several decades, Intravacc has positioned itself as a global leader in the development of vaccines aiding in the eradication of Polio and has engaged in the research and development of bacterial and viral vaccines against, amongst others, Respiratory Syncytial Virus (RSV), Shigella, Rotavirus, Hib and DTP.

Intravacc was originally formed to perform public tasks concerning research and development of new vaccines resulting from the ambitions and objectives set out by the Dutch State. The company’s aim is to develop safe, effective and affordable vaccine concepts in order to find sustainable solutions to improve public health worldwide. Intravacc is located in Bilthoven, the Netherlands, where it operates state-of-the-art R&D and Good Manufacturing Practice (GMP) facilities for conducting vaccine research.

As a result of the increasing commercial focus of the organization and its close collaboration with the (global) pharmaceutical industry and Global Health parties such as the World Health Organization and the Bill and Melinda Gates Foundation, MoH decided Intravacc would be better suited in a private setting. In June 2015, the Minster of MoH informed the Dutch House of Representatives on its intent to privatize Intravacc and, has now obtained all required political approval to commence the privatization process in order to secure a suitable prospective buyer.

Collegium Corporate Finance and Valuation Advisors has been appointed to act as lead advisor to the MoH during the privatization of Intravacc. Collegium will aim to inform potential prospective buyers about the timelines and structure of the privatization process. Any contact and all expressions of interest with regards to the privatization process should be expressed via Collegium (Intravacc@CollegiumAdvisors.com).

CVB, an enterovirus, has been identified as a possible common trigger for type 1 diabetes (T1D) onset. Vaccination of at-risk populations against CVB infection may lead to the prevention or delay in onset of T1D. The CVB vaccine was developed initially by Vactech Ltd. of Finland and licensed to Provention in April, 2017. Provention is planning to initiate first in-human clinical trials in 2020.

Enteroviruses are responsible for an estimated 30 million infections annually in the US. CVB contributes significantly to enteroviral healthcare costs, since it can result in hospitalization and severe morbidity. Usually asymptomatic or presenting as cold-like symptoms, fever, rash, hand-foot-mouth disease, and/or mild gastrointestinal distress, CVB infections can occasionally cause more serious and sometimes lifethreatening illnesses including pericarditis, myocarditis, meningitis and pancreatitis.

Provention, in partnership with Intravacc, Vactech and L2D is now developing its CVB vaccine for large scale manufacture of clinical trial material in accordance with current Good Manufacturing Practices (cGMP). Intravacc was chosen as Provention’s manufacturing partner based on its expertise and excellent track in enterovirus vaccine development, including IPV, sIPV, EV-71, and CV-A16, as well as Intravacc’s state-of-the-art vaccine cGMP production facilities. PRV-101 will be developed using Intravacc’s proven and well-established platform technology, including certain proprietary cell lines and production processes.

Ashleigh Palmer, co-founder and CEO of Provention Bio, stated, “Selecting Intravacc for PRV-101’s cGMP production is an important next step in our plan to initiate a potentially transformative clinical program to develop a vaccine to prevent acute coxsackievirus B infection and, ultimately, prevent or delay the onset of as much as half of the world’s cases of T1D. We welcome this opportunity to work alongside Intravacc, Vactech and L2D to advance our PRV-101 program to the clinic.”

Intravacc’s CEO Thijs Veerman, MSc, commented, “We are very excited to be involved in this project. Intravacc is uniquely positioned to develop cGMP clinical material for this vaccine and ensure its specifications, quality and patient-readiness. We have the necessary knowledge, expertise and experience to advance Provention’s PRV-101 program to the next stage and beyond.”

About Type 1 Diabetes and Coxsackievirus B Infection

T1D is a life-impacting chronic disease caused by immune destruction of the insulinproducing cells in the pancreas. Today, there is no cure. The only means for managing this devastating disease is life-long blood glucose monitoring and insulin replacement by way of injection, infusion or, potentially, pancreatic cell transplantation. Global longitudinal studies of more than 200,000 children screened, and more than 17,000 followed, over two decades in Finland by Vactech’s scientific founders and collaborators have identified CVB infection as a likely trigger for T1D onset. From this research, it was discovered that the diabetes process often starts after CVB infection. Insulin-producing cells in the pancreas express specialized receptors used for cellular infection by CVB. As a result, an exacerbated immune reaction against the virus may be involved in triggering the autoimmunity targeting the pancreas and gut, which appears to precede the onset of T1D and associated celiac disease. Importantly, the CVB-related risk of T1D autoimmunity was significantly reduced in children whose mothers previously had a CVB infection, thereby suggesting a transfer of protective CVB antibodies to their offspring via placenta and breast milk. This observation suggests the potential benefit of CVB vaccination for children.
